OnAfterHolidayRemoved Method

Raises the AfterHolidayRemoved event before a Holiday is removed from the Holidays collection.
Syntax
'Declaration
 
Protected Overridable Sub OnAfterHolidayRemoved( _
   ByVal e As EventArgs _
) 
protected virtual void OnAfterHolidayRemoved( 
   EventArgs e
)

Parameters

e
A System.EventArgs that provides data for the event.
Remarks

Raising an event invokes the event handler through a delegate.

The OnAfterHolidayRemoved method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Holidays to Inheritors: When overriding OnAfterHolidayRemoved in a derived class, be sure to call the base class's OnAfterHolidayRemoved method so that registered delegates receive the event.

Example
This example informs the end user than a Holiday was removed from the collection, prompting to see if they would like to add another holiday for the ActiveDay.
